FreeRTOS and heap_4_infinitime.c.
LVGL supports custom implementation of malloc() and free() so using pvPortMalloc() and vPortFree() is just a matter of setting the right variables.
Other libraries (NimBLE, LittleFS) and InfiniTime code (new) call malloc() and free() from stdlib. InfiniTime now provides the file stdlib.c that provides a custom implementation for malloc(), free(), calloc() and realloc(). This ensures that all calls to the standard allocator are redirected to the FreeRTOS memory manager.
Note that realloc() is needed by NimBLE.

lowest priority (0). Both display and system tasks are also set on priority 0.
In cases where any other task takes too much time to execute (it can happen in Display Task, see https://github.com/InfiniTimeOrg/InfiniTime/issues/825), the timer task does not have the opportunity to run fast enough to detect and debounce presses on the button.
This commit sets the following priorities:
- [0] : Display Task
- [1] : Timer and System tasks
- [2] : BLE Host
- [3] : BLE LL
This way, we ensure that button presses will always be detected, even if the rendering of the display takes a huge amount of time.

variable instead of variables on the heap. We don't need them on the heap as we know their size at build time, it'll reduce memory fragmentation and it'll make memory analysis easier.

- Disable IDLE hook (it would wake the device up as soon as possible).
- Logger task sleep for 100ms (disable logging for better battery life)
- Logging is disabled by default
- Apply fix for ERRATA 87 (clear FPU interrupt before going to sleep). Ports files from FreeRTOS are now in the sources (they where in the SDK before)
